If you weighed out a small sample of sodium acetate, then dumped it into a beaker of water and stirred it around, which of these statements would NOT be true? a. The the sodium acetate will fail to dissolve b. The solution will conduct electricity. c. Individual sodium and acetate ions are present. d. none of the above

Respuesta :

Answer:

The statement that isn't true is the a)

Explanation:

The sodium acetate when mixed with water dissociates:

[tex]Na(CH_3COO) \longrightarrow Na^+ + CH_3COO^-[/tex]

So we can affirm that this ions will dissolve in water (a polar solvent) and individual ions of sodium and acetate will be present in the solution. Also, the presence of ions in water increases its electrical conductivity.

Being all that said, the statement that isn't true is the a)

a) The the sodium acetate will fail to dissolve

Explanation:

The sodium acetate when mixed with water dissociates:

[tex]Na(CH_3COO)[/tex] → [tex]Na^+ +CH_3COO^-[/tex]

  • When sodium acetate is dissolved in water, it is hydrolyzed. In water, sodium acetate splits into sodium and acetate ions. The sodium ions react very little with the hydroxide ions, but the acetate ions form acetic acid when they mix with hydrogen ions.
  • So, we can affirm that this ions will dissolve in water (a polar solvent) and individual ions of sodium and acetate will be present in the solution. Also, the presence of ions in water increases its electrical conductivity.

Therefore, option a is correct.
